[link to hvo.wr.usgs.gov] Activity Summary: Kilauea continued to erupt at two locations: At the summit, stable conditions and minor fluctuations of the lava lake continued. In the east rift zone, lava flowed onto the Pu`u `O`o crater floor through most of yesterday and slowly advanced northeast of the cone on older flows to the north of Pu`u Kahauale`a. To the southeast of Pu`u `O`o, lava was entering the ocean in multiple areas both inside and outside the National Park boundary. Gas emissions remained elevated.... [link to hvo.wr.usgs.gov]

brief description of this paroxysm [link to volcans.blogs-de-voyage.fr] ... lava fountaining at about 5 o’clock this morning, with lava flows that travelled down the western slope of the Valle del Bove. A voluminous ash plume was also observed. According to the EtnaWalk website, “the lava fountains originated from several vents aligned east-west and sometimes reached a height of 1,000 metres or so”...

Ok, excellent, now continue with a clean slate.

found an interesting link on 18th century natural phenomena1755, when Katla erupted big, was a FUN year.. [link to www.phenomena.org.uk] a lot of shit happened to europe that year. a repeat would send this forum into meltdownread through the other years as well. a shitload of stuff happened in the past

Thank you for an interesting chronicle of events, there is something to think about!

Totally agree with you that such a steam as it is today was shot over the Hekla [link to i1164.photobucket.com] we are for the last two years of observations of volcanoes in Iceland have never seen, over Katla too!

This remarkable event i guess also confirms our thinking that the most likely candidate for an eruption in the near future is a volcanic complex from Hekla to Torfajokull. Of course, we will watch it closely further.

Meanwhile, the celebration of the birth of this thread is continuing, and it coincided with already one hundredth of the account page!All of which contain the most rapid, complete and accurate information about what is happening with the volcanoes in the world )

...Within the Pu`u `O`o crater, the southwestern spatter cone continued to issue a small amount of lava; at about 1 am, there was a large amount of lava issued from the south side of the northeast spatter cone that was largely out of direct view of our Webcam array; this early morning breakout also resulted in new breakouts on the Kahauale`a tube high on the northeast flank of Pu`u `O`o cone. The tiltmeter on the north flank of Pu`u `O`o cone recorded fluctuations with an abrupt 1.3 microradian drop accompanying the above-mentioned crater-floor activity. Seismic tremor levels near Pu`u `O`o remained low. The most recent (preliminary) sulfur dioxide emission rate measurement was 300 tonnes/day on February 12, 2013, from all east rift zone sources. Outside the crater and across the northeast flank of Pu`u `O`o cone, multiple lava flow lobes, informally called the Kahauale`a flow, continued to be active northeast on older Pu`u `O`o flows north of Pu`u Kahauale`a to the base of the 2007 perched channel (visible in Pu`u `O`o East Thermal and North Webcams); it's too early to tell whether the early morning activity from the NE spatter cone, the source of the Kahauale`a flow, will affect the Kahauale`a flow progress...

description [link to volcans.blogs-de-voyage.fr] ... Just like yesterday, there were lava fountains several hundred metres high which stopped at 02:40 or so. Meantime, the effusive activity from a new vent at the base of the cone continued until about 6 o’clock this morning. Like before, lava travelled down the Valle del Bove.

Interesting new data about caldera's ice cap last autumn survey:

...Latest measurements (26 November 2012) Results of the 3 latest surveys and the survey on December 17 1999 are shown on the profiles below. Ablation in summer lowers the surface elevation of the glacier by 4-8 m from spring to autumn. Accumulation of snow restores the elevation during the winter. From autumn 1999 to autumn 2001 cauldron 7 gradually got shallower but apart from that changes were not significant. Between autumn 2001 and 2004 some cauldrons grewn, due to increasing geothermal activity. This increase was accompanied by increased seismicity and uplift (www.vedur.is), the cause probably being magma accumulation under the Katla caldera. After 2004 geothermal activity declined until a sudden increase caused the flood in M&#250;lakv&#237;sl 9 July 2011. Mainly cauldron 16 and 9 grew in size but changes could also be seen in cauldrons 8 and 10...

The island was constructed during the past 150,000 years, with three cone-building stages including explosive and effusive andesitic eruptions and effusive and extrusive dacitic and rhyolitic activity. The age of the caldera is variously considered to be <24,000 years before present (BP) (Keller et al., 1990) and >44,000 years BP (Limburg and Varekamp, 1991).
